They divorced in 2009 and since then, haven't always seen eye to eye.

They recently patched things up, after Katie offered a grovelling public apology to him on Twitter .

But ever since they went their separate ways, their lives have been very different.

Just a couple of months after splitting from Peter, Katie started dating MMA fighter Alex Reid.

They married in 2010 but separated just 11 months later.

She went on to marry former stripper Kieran Hayler in 2013. Together, they had children Bunny, five, and Jett, four, before splitting last year.

The pair are yet to divorce, but Katie, who is also mum to Harvey, 17, is engaged to personal trainer Kris Boyson.

Katie has had some recent brushes with the law, being handed a restraining order against ex Kieran's new girlfriend Michelle Pentecost after an altercation at children Jett and Bunny's school, and she was banned from driving after being found guilty of being drunk in charge of a motor vehicle.

She's also been pictured bloody and bandaged following her recent round of plastic surgery.

Katie recently visited the Comfort Zone Surgery Clinic in Istanbul, where doctors cut an incision along her ear and hairline to pull her facial tissues taut.
